Exporting DBCP and other banned pesticides: consideration of ethical issues

Mortality among a Cohort of Banana Plantation Workers in Costa Rica

The nematocide 1,2-dibromo-3-chloropropane (DBCP), widely used in Costa Rica during the late 1960s and 1970s, causes sterility in men and is a possible carcinogen. Mortality among a cohort of Costa Rican banana plantation workers was investigated. The cohort included 40,959 individuals who worked on banana plantations between 1972 and 1979. Employment records were linked with the Costa Rican Mortality Registry to determine outcomes through 1999. Standardized mortality ratios (SMRs) were calculated for all causes of death. Poisson regression was also used to calculate mortality risk estimates by duration of employment, but provided no additional insight. All-causes SMRs were 0.77 for men (95% CI 0.75-0.80) and 0.90 for women (95% CI 0.80-1.02) relative to national mortality rates. Mortality from septicemia was significantly higher than expected. Nonsignificant increases in mortality were also observed for testicular cancer, penile cancer, Hodgkin's disease, and Parkinson's disease in men, and for cervical cancer and lung cancer in women.

Social movements and risk perception: unions, churches, pesticides and bananas in Costa Rica

BACKGROUND

Between 1992 and 2010 in the Costa Rican Caribbean, a social movement coalition called Foro Emaús sought to change people's view on problems of high pesticide use in banana production.

OBJECTIVE

To understand the formation and membership of Foro Emaús, its success period, and its decline.

METHODS

Semi-structured interviews of 28 key actors; a questionnaire survey among school personnel (n = 475) in Siquirres, Matina, and Talamanca counties; and secondary data from newspapers, leaflets, and movement documents were used.

RESULTS

Foro Emaús developed activism around pesticide issues and put pressure on governmental agencies and banana companies and shaped people's perception of pesticide risks. The success of the Foro Emaús movement led to the reinforcement of a counteracting social movement (Solidarismo) by conservative sectors of the Catholic Church and the banana companies. We found that the participation of unions in Foro Emaús is an early example of social movement unionism.

CONCLUSIONS

Scientific pesticide risk analysis is not the only force that shapes emerging societal perceptions of pesticide risk. Social movements influence the priority given to particular risks and can be crucial in putting health and environmental risk issues on the political and research agenda.

Transfer of occupational health problems from a developed to a developing country: lessons from the Japan-South Korea experience

Many corporations move their manufacturing facilities or technologies from developed to developing countries. Stringent regulations have made it costly for industries to operate in developed, industrialized countries. In addition, labor costs are high in these countries, and there is increasing awareness among the general public of the health risks associated with industry. The relocation of hazardous industries to developing countries is driven by economic considerations: high unemployment, a cheaper labor force, lack of regulation, and poor enforcement of any existing regulations make certain countries attractive to business. The transfer of certain industries from Japan to Korea has also brought both documented occupational diseases and a new occupational disease caused by chemicals without established toxicities. Typical examples of documented occupational diseases are carbon disulfide poisoning in the rayon manufacturing industry, bladder cancer in the benzidine industry, and mesothelioma in the asbestos industry. A new occupational disease due to a chemical without established toxicities is 2-bromopropane poisoning. These examples suggest that counter-measures are needed to prevent the transfer of occupational health problems from a developed to a developing country. Corporate social responsibility should be emphasized, close inter-governmental collaboration is necessary and cooperation among non-governmental organizations is helpful.

The global expansion of precarious employment, work disorganization, and consequences for occupational health: placing the debate in a comparative historical context

Mounting research evidence suggests that the shift to contingent work arrangements in industrialized countries is having serious adverse effects on the health of workers, both directly and indirectly (by undermining regulatory and other protections). The authors place this research, and the issues surrounding it, in a comparative historical context. Extensive use of precarious employment is not essentially new. It was a characteristic feature of most if not all industrialized societies in the 19th and early 20th centuries. Though the two phases are not identical, historical comparisons are instructive for understanding recent experiences and ways of addressing them. The authors also make comparisons with the developing world, where the informal sector typically accounts for over half the workforce. Such comparisons are instructive in indicating the consequences of a shift to more precarious patterns of employment and disorganized work settings. There is also good evidence that precarious employment is expanding in the developing world. The growing precarious employment in both industrialized and developing countries is interconnected, and the authors identify a number of the mechanisms affecting workers' health.

Ethical and practical aspects of human studies

Increasingly, genetic information holds the promise of prevention, earlier detection, and better treatment for cancer and other genetically related diseases. Laboratory markers are giving insight into the role of measurable genetic changes; however, there is often difficulty in translating laboratory data into practical use in human populations. Human populations can be difficult to study, and, correctly, there are strict regulations regarding the use of humans as study subjects for many kinds of research activities. Various study designs have a differential ability to prove cause and effect relationships, and will similarly have a differential ability in validating the usefulness of genetic markers. Just as conducting bench research has a traditional set of problems, working with human populations has its own set of potential difficulties. In reality, workers and others are often exposed to carcinogenic substances, usually without their knowledge, and without their informed consent. As genetic information becomes more readily available, and in finer detail, there is a great risk of misuse by employers, insurance companies and others. Placing blame on someone's genetic make-up may once again put into vogue a "blame-the-victim" mentality instead of continuing efforts to clean up workplaces and the environment, or restricting the use of hazardous products. No genetic information should ever be used to deny employment or modify insurance rates. Individuals should be able to maintain personal control over their genetic information. Positive aspects of the use of genetic information can be used to decrease disease and make environments safer.
